Hi, I bout a 3-user license of ESS from Amazon.co.uk. They even delivery to Sweden, where I live. No problm. Got the packaged with ESS inside within a week. On the manual inside the ESS box, was the Serial Number written. So I went to the UK ESET homepage to activate my license and to get the username and password. http://www.eset.co.uk/activate Filled in all data, Selected "Sweden" as country, entered my adress and postcode, e-mail and so on. But when I pressed enter, ESET.co.uk did not accept my address. Maybe because it was not a UK address. I don't know which postcodes are existing in UK and so on. So I went to the Swedish ESET distributors homepage to register there. But after entering the information I got the message "Serial Number incorrect". So I made a third try and went to the USA homepage for ESET. But got the same there, Serial-Number is not valid. What I finally had to do was, I went out on google and searched for "postcodes london" and found the homepage Londontown.com. On this homepage I found the postcode "SW1A 0RS" which was working on ESET.co.uk. Entering this postcode in the activation homepage and got a road I could select. Picked this road and completed the rest of the Activation form. A new window comes up where I had to write the reseller. I wrote "Amazon" and could select the Amazon-Shop from a list. First now I could activate the license and got the username and password via E-mail. Unbelievable which difficult procedure! The swedish ESET distributor don't ask for the whole homeadress when registering a license. But they didn't accept the serial number from the ESS product bought via Amazon.co.uk. Can anyone address this to the ESET support? Why has it to be so difficult to activate a license. - Ok I saved a lot of money buying the license via Amazon compared to buying it via the ESET homepage, but anyway I don't like the procedure which I was required to do to get my UK ESET License activated.
